"So Namjoon, but the leader position doesn't prove that you aren't the one who killed him", thought Jungkook loudly and smirked. "Smart", considered Taehyung, "very smart, Jungkook."
"Please, Jungkook, say that I misheard you", whimperd Jin. 

"Do you know what, Jungkook!? I don't fucking care what you think about me! I just swear with my damn life that i didn't kill our little Jimin! I don't care if you belive me or not, Jeon Jungkook. 
Fact is: One of us is a murder!", screamed the leader.

Everybody looked toxic at each other again. Just Jin stayed calm. "He really believe that we are all innocent", though Taehyung shaking his head. 

"I'm done with you! With all of you! One of you killed my friend!", Hoseok yelled stressed and leaved the room. The oldest of the members went after him. 

"Without joking now. Who did it?", the words of the leader were soft. "How can a person that cruel?" He no longer sounded aggressive but rather sad and vulnerable.
"Namjoon"; Jungkook began, "I know Jimin was like a little brother to you. But you have to let him go. We all have. But i swear you, the murder will be founded and punished as sure as my Name Jeon Jungkook is. Promise."

Taehyung was visibly impressed by Jungkook's role as the innocent. Yes, he played fantastically, no doubt about it. No one would be able to see through him.

"I need some fresh air." With this words the leader leaved the room. "I have to sleep", Yoongi explained, "the day was so stressful" The rapper yawned and leaved too. 

Now there was only Jungkook and Taehyung. "Don't do that!", the maknae hissed like a snake. "You have to pretend like you are innocent. You have to act like you are shocked. Did you understand me Kim Taehyung? If they find out, they would put us in the prison!"
Taehyung swallowed the huge lump in his throat, which had only increased due to Jungkook's shouting, and then said; "What are you talking about? We... we aren't murders..."
"So? What we are then"; Jungkook smirked. It was an accident Jungkook, you know that. We just wanted to play a harmless prank on him. Just a prank," Taehyung complained wryly.

"I know it was an accident. But they won't believe us, Tae! ", Jungkook's face was so close to Taehyung's that he had trouble not flinching."Jungkook, we are murderers. I don't know how long I can live with this knowledge," he whimpered.  "We aren't killers", Jungkook said, "it's right, i injured Jimin and exactly that was the accident. Everything else that happened afterwards is your responsibility. I didn't pull the trigger, you did! I may be blame.
But in the end, I didn't kill Jimin, you did."
